In the mid-1990s, I had a local doppelganger - "the lady from Teddybears Playgroup". One day quite randomly a lady in the corner shop asked me if I'd gone into childminding as I'd said I was planning to do, when we were on that childcare course together. Er...no, I hadn't done a childcare course!
A year or so later, I answered the door to two Jehovah's Witnesses, one of whom was certain he knew me because his toddler attended Teddybears Playgroup. My own three-year-old had just started at an entirely different playgroup which had a rota for "voluntary" parent helpers, and I had been wondering why the organisers had put my name down three times as often as anybody else's...
After that, I think Teddybears Lady must have moved away because things went quiet for two or three years, and then an old lady at a bus stop greeted me like a long-lost friend before saying, "...But you can't be here. You're still in Northampton!" Apparently she'd just moved to my small town in Sussex to be closer to her grandchildren, didn't yet know anybody locally, but then unexpectedly saw a familiar face - her former next-door-neighbour's daughter - walking towards her. Her name was Ethel, and we ended up firm friends for many years.
By an odd coincidence, I took a short-cut through the estate where Ethel used to live this morning, and an old man walking his dog waved to me from the other side of the road and called, "Happy New Year, Maggie!"
No, my name isn't Maggie. But I bet my newest doppelganger's is!
